Can anyone tell me the size of the nut that holds the oil cooler line in on the rear of the block?

18mm x 1.5
If you need one,I may just have one.
If it is leaking,the common mistake is that crush washers that are used to seal the line to the rear of the engine,and they get lost..so leaky.leaky..(18mm copper crush washers)

 

The size of the banjo bolt's head is 23mm.

 

..or you can get away with 15/16th's.

 

Every rotary owner has a 23MM socket in the tool box just for this purpose.

And a (22MM?) wrench ground thinner for the oil cooler line on the front cover.

 

I never go anywhere without my DREMEL!

 

i measured the two on the front of the block and they are and 21 and 26
